It is necessary to deter the host from sending subsequent DFU_GETSTATUS
request in the case of e.g. writing the buffer to medium.
Here the timeout is increased when we fill up the whole buffer. This delay
allows eMMC memory to perform its internal operations.
Otherwise we end up with HOST's error regarding GET_STATUS receive timeout.

This patch extends dfu code to support transmission with -R switch
specified at dfu-util.
When -R is specified, the extra USB_REQ_DFU_DETACH request is sent after
successful data transmission. Then dfu resources are released and reset
command is issued.

This subtle change fix problem with too small amount of allocated
memory to store DFU function pointers.
One needs to allocate extra space for sentinel NULL pointer in this array
of function pointers.
With the previous code, the NULL value overwrites malloc internal data
and afterwards free(f_dfu->function) crashes.

- set in to_dfu_mode() f_dfu->dfu_state = DFU_STATE_dfuIDLE
as after every to_dfu_mode call this is done, so move
this into to_dfu_mode
- switch in dfu_bind() into dfu mode:
This fixes wrong "dfu-util -l" output, when calling
"dfu-util -l" after a board reset, without doing a
download before. See also discussion here:

Zero out timeout value; letting it filled with undefined values
ends up with the dfu host hanging.
